Machine Data | Introduction

The Machine Data tab is used to model a synchronous machine with internal faults such as inter-turn fault, phase-to-ground fault, phase-to-phase fault, etc. Since the internal fault model requires numerous parameters that are computed from standard parameters and winding information, a parameter generator was introduced directly in the mask of the machine with internal fault.

	Compute	It uses the provided information to generate all the parameters required by the simulation model.
	Revert	It reverts to the default preparation data.
	Browse	It is used to load preparation data. The required format is .hmd for HYPERSIM Machine Data.
	Save	It is used to save preparation data as a .hmd file (HYPERSIM Machine Data files)
	Load parameters	It loads the computed parameters into the component.

Sub-tab	Description
Parameters	it contains general information and user comments to be saved in the Hypersim machine data (.hmd) file. The rotor type has an impact on the number of rotor circuits on the q-axis. A salient-pole machine has a single q-axis damper while the round-pole machine has two.
Standard	it is used to enter the standard parameters per unit (p.u.) and convert to fundamental parameters. It computes the standard parameters associated with the fundamental parameters displayed for comparison.
Fundamental	It is used to enter the fundamental parameters per unit (p.u.) and convert to standard parameters
Winding	It contains the necessary winding parameters. A winding file must be loaded and corresponding parameters will be displayed. The format of the winding file, as well as the required information, are given at the end of this document.
Fault	It allows the user to provide the winding information as a .m file (MATLAB program file).
Log	It displays the machine data report after the computation has run.
